Integra Sources vs QuEST Global: overview
Integra Sources
Integra Sources, founded in 2014, is a compact turnkey hardware-and-firmware shop with public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (roughly 24 to 51 employees). Kazakhstan is an unusual but genuine offshore-cost outsourcing base — outside the more commonly discussed Eastern Europe/South Asia corridors — and the firm reports 250+ completed IoT and embedded projects, a useful volume signal for a small team at this cost tier.
QuEST Global
QuEST Global, founded in 1997 and headquartered in Singapore, operates over 90 delivery centers across 18+ countries — one of the broadest global outsourcing footprints on this list. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), itself a sign of a firm too large and diversified for a single precise headcount. Embedded and silicon engineering is one capability among many verticals rather than a dedicated outsourcing specialty.
